Blow-mould case for storage and mobility

The durable case keeps all 57 pieces organised and protected during transport. Hand tools carry a limited lifetime warranty while mechanics tools have a full lifetime warranty. The set measures 15.12 inches overall, fitting standard toolbox compartments.

Questions about this item

Does the 72-tooth ratchet's 5 degree arc swing generate heat or noise during extended use?

The 72-tooth ratchet operates mechanically with a 5 degree arc swing and has no motor or electrical components, so it produces no heat or audible noise during all-day use.

What drive size must I already own to use the sockets included in this 57-piece set?

The mechanics tools in this set use a 1/4-inch drive, so no separate drive tool is required; the included low-profile ratchet fits the sockets directly.

Will the low-profile ratchet head, which is up to 25% thinner than the CMMT81747, work alongside my older Craftsman sockets?

Yes, the ratchet uses a standard 1/4-inch drive interface compatible with existing Craftsman sockets of the same drive size.
